Detailed explanation-1: -As you saw in the previous module, situations involving growth (or decay) in which the output quantity changes by a constant amount per unit of input are said to exhibit linear growth. That is, from one input to the next, there is a common difference between the output values.
Detailed explanation-2: -A quantity grows linearly if it grows by a constant amount for each unit of time.
Detailed explanation-3: -INCREASING AND DECREASING FUNCTIONS The slope determines if the function is an increasing linear function, a decreasing linear function, or a constant function. f(x)=mx+b is an increasing function if m>0. f(x)=mx+b is a decreasing function if m<0.
Detailed explanation-4: -f(x) = a + bx Algebraically, linear functions are a two parameter family. The parameter a is called the function’s y-intercept and the parameter b is called the slope. Together, they completely determine a linear function’s input-output behavior. Notice that f(0) = a : The y-intercept is the output when the input is 0.
Detailed explanation-5: -A linear relationship is one where increasing or decreasing one variable n times will cause a corresponding increase or decrease of n times in the other variable too. In simpler words, if you double one variable, the other will double as well.
